摘  要

本文介绍了一种块DWC300双扭结巧克力糖果包装机的控制方案，从软、硬件两方面阐述了系统的组成和功能。根据糖果包装工艺特点，本系统流程主要为推搪-包糖-喷胶-截断。以三菱FX2N系列PLC为控制核心，利用PLC的强大功能，以松下VF0变频器控制一台三相异步电机完成上述流程，同时电气装置也能够按照设计要求稳定运行。本系统外部电路简单，具有微型化和低能耗的特点。此外，本系统加强了人机互动，利用力控组态软件开发了DWC300双扭结巧克力糖果包装机控制系统界面，实现包装过程的自动跟踪与监控。组态软件是新型的工业自控控制系统，它以标准的工业计算机软、硬件平台构成的集成系统取代传统的封闭式系统。

DWC300 双扭结巧克力包装机适用于单粒有规则形状物品的双扭结包装等，如巧克力。输送带输入并通过机械将物料推入理糖盘进行的扭结包装；光电跟踪，触摸式液晶显示及PLC控制；可选配定制成转盘自动理料或整理线自动理料。

Abstract

This paper introduces the control scheme of a DWC300 double kink chocolate candy packing machine, and expounds the composition and function of the system from the aspects of software and hardware. According to the technological characteristics of candy packaging, the system process is mainly for lining-wrapped sugar-spray-cut-off. Taking Mitsubishi FX2N series PLC as the control core and using the powerful function of PLC, a three-phase asynchronous motor is controlled by Panasonic VF0 inverter, and the electrical device can run stably according to the design requirements. The external circuit of the system is simple and has the characteristics of miniaturization and low energy consumption. In addition, the system enhances man-machine interaction and utilizes force control configuration. The control system interface of DWC300 double kink chocolate candy packing machine is developed to realize the automatic tracking and monitoring of packing process. Configuration software is a new type of industrial automatic control system. It replaces the traditional closed system with the integrated system composed of standard industrial computer software and hardware platform.

DWC300 double-kink chocolate packing machine is suitable for single-grain double-kink packaging such as chocolate. Conveyor belt input and mechanical material into the sugar plate for kink packaging；photoelectric tracking, touch LCD and PLC control；can be customized into automatic rotating plate material or finishing line automatic cutting material.

Key words: DWC300；double kink；chocolate candy packing machine；force control configuration software
